With the VMPS-4, not only do you avoid the tap dancing, you also simplify your pedalboard with the power supply already incorporated.
Why you should buy the VMPS-4?
You want to simplify switching your effects in your pedalboard
You are combining analog and digital pedals – you need to reduce the noise by using an isolated power supply to isolate the digital effects and also isolate the noisy pedals from the chain when not in use.
You want a streamlined board with the switcher and power already integrated.
